FEED-WATER APPARATUS FOR LOCOIVIOTIVE-ENGINES.

Specification of Letters Patent No. 27,662, dated March 27, 1860.

To all whom it may concern:

Be it known that I, R. A. 1WILDnn, of Schuylkill Haven, in the county ofSchuylkill and State of Pennsylvania, have invented a newand usefulImprovement in the Method of Supplying Feed-Tater to the Boilers ofLocomotive-Engines, of which the following is a full and exactdescription, reference vbeing had to the accompanying drawing, of which-A represents the apparatus in place on the side of the boiler, justbeneath the check valve, and Figures l, 2, and 3, represent theapparatus in separate parts.

My invention consists in the arrangement of a two way valve,in'connection with the pump, the overflow pipe and the feed pipe bywhich the supply of feed water may be so regulated that any desiredquantity may be conveyed to the boiler and a surplus if any be conveyedthrough an overflow pipe back to the tank. By this arrangement the pumpmay be kept in constant use thereby lessening the chances of its gettingout of order and preventing it from freezing up in cold weather.

The dra-wings clearly illustrate and eX- plain the construction and useof my improvement.

a is the rod by which the engineer moves the arm.

o is an arm which attached to the valve regulates the direction of theflow of water.

c is a pipe connecting the pump with the valve chamber.

d is a pipe conveying the overflow of water back to the tank.

e is a hose connecting the overflow pipe with the tank.

f is a hose to convey the feed water from the tank to the direct feedpipe.

F ig. l represent-s the valve arrangement separated from the engineboiler. Fig. 2 is the valve and packing box. Fig. 3 is the arm or thelever by which the valve is moved.

YVhen it is not necessary to feed the boiler the valve is set so as tobring the opening in it in line with the pipes c and d, the pressure ofthe steam in the boiler keeps the check valve from lifting and the waterpasses from the pump through the pipe back to the tank. When the valveis moved so as to close the overflow pipe d all the water is forced intothe boiler and hence it will be readily seen that by placing the valveat any point between the two positions described a portion of the waterwill be forced into the boiler' and a part flow back to the tank. By myimprovement the supply of water to the boiler may be constant andadapted to the quantity evaporated under all circumstances.

Claim- The arrangement substantially as herein shown and described, inconnection with the feed and overflow pipes and pump, of a tw o waycock, so that while a constant circulation of water is maintainedin saidpipes, only such portion thereof as may be desired shall enter theboiler, all as set forth.

In witness whereof I have hereunto subscribed my name the 27th day ofMarch, eighteen hundred and fifty seven.

R. A. VVILDER.
